分析商业片段筛选集合中的化学空间覆盖率表明,生物活性药物化学子结构和符合三规则的片段之间的重叠率仅为 ∼25%。我们建议将这些片段包含在片段筛选文库中,以最大限度地提高在已知生物活性化学空间内发现命中物质的信心,同时合并不重叠的子结构可以在筛选文库中提供新的命中。使用主成分分析,极性和三维子结构显示出生物活性化合物的富集度高于平均水平,表明这些子结构的代表性的增加可能有利于片段筛选。
Analyzing the chemical space coverage in commercial fragment screening collections revealed the overlap between bioactive medicinal chemistry substructures and rule-of-three compliant fragments is only ∼25%. We recommend including these fragments in fragment screening libraries to maximize confidence in discovering hit matter within known bioactive chemical space, while incorporation of nonoverlapping substructures could offer novel hits in screening libraries. Using principal component analysis, polar and three-dimensional substructures display a higher-than-average enrichment of bioactive compounds, indicating increasing representation of these substructures may be beneficial in fragment screening.
